Carlson, Brooklyn, N. Y., assignor to International Cigar Machiner Company, a corporation of New Jersey Original application August 16, 1939, Serial No. 290,422.

Claims.

This invention relates to cigar machines and more particularly to improvements in wrapper transfer mechanism for use on cigar machines, and constitutes a division of my co-pending application, Serial No. 290,422 filed August 16, 1939, for Cigar machine wrapper transfer mechanism.

It is an object of this invention to provide novel wrapper transfer mechanism which is simple in construction, easily adjustable and of a type especially adapted for use in conjunction with cigar wrapping mechanism in which the cigar wrapper carrier head is adapted to travel along a continuous and closed path during the operation of the machine.

It is a further object of the invention to provide a suction wrapper carrier head which is provided with two compartments divided by an apertured wall and a gravity biased valve for closing the aperture, but which, due to the fact that the head is generally adapted to move along a closed path during the operation of the machine, is provided with a valve stem projecting exteriorly of the casing of the head, and has secured thereto a lever provided with a cam follower so arranged that during the movement of the carrier head to wrapper applying position, the cam follower will engage a cam and move the valve from normally open to closed position for diverting all of the suction into one compartment.

It is a further object of my invention to provide an improved suction wrapper carrier head which is more durable in construction, has fewer parts, is less expensive to manufacture, and will stand up under operating conditions with less wear and tear, and consequently require fewer repairs.

With these and other objects not specifically mentioned in view, the invention consists in certain combinations and constructions which will be hereinafter fully described, and then specifically set forth in the claims hereunto appended.

In the accompanying drawing which forms a part of this specification, and in which like characters of reference indicate the same or like parts: I

Figure 1 is a partial side elevation partly in section of the improved wrapper transfer; and

Figure 2 is an end view of the same taken fromv line 2--2 of Figure 1.

Referring to Figures 1 and 2, the improved wrapper transfer mechanism is mounted on a hollow column (notshown) which may be of the same general type as that shown inthe United States Patent No. 2,235,857, granted March 25, 1941, to Henry H. Wheeler for Wrapper carrier operating mechanism, attached to the base plate of a cigar rolling machine (not shown), and connected to its suction system in the customary manner. The column has a horizontal arm l0 terminating in a hearing I l in which is journaled a hollow shaft l2 closed at its ends by removable plugs 13 and [4. v

A gear [5 fixed on the hollow shaft I2 is driven in the same manner as disclosed in said patent above referred to, and therefore, in the interest of brevity, a more detailed showing and description of the same is omitted.' To the lower end of shaft I2 is clamped a hollow arm l6 which is provided with a bearing Il pivotally supporting a hollow arm 18 joined to arm I6 by a bolt IS. The free end of arm l8 forms a bearing for a holder 20 secured to a vertical shaft 21 turning in the bearing and carrying a suctionwrapper carrier head 22. From the free end of arm l8 projects a lateral extension 23 which mounts cam follower 24. To the upper end of shaft 2|, which extends from the free end of arm I8, is fastened a cam piece. 25 carrying a roller 26. The followers 24 and 26 engage in cam tracks provided in the under side of a stationary cam 21 attached to bearing II, the follower 24 guiding the shaft 2| in a predetermined path and the follower 26 in each position on this path swinging the carrier head 22 to the proper angle for applying the wrapper W to the particular cigar shape for which the cam 21 is designed. The carrier head 22 is adapted to travel through a closed path each cycle of the machine from wrapper receiving to wrapper applying station and back to receiving position, all as disclosedin the above referred to Wheeler patent.

At proper points, the cam 21 has projecting studs carrying followers 28 and 29 adapted to be engaged by the cam piece 25 in the manner described in the above mentioned patent and thereby turning the shaft 2| and reversing the carrier head 22 after the same has delivered the wrapper and is returning to its receiving or pickup position. In the pick-up position shown in Figure 1, the carrier head 22 rests over the lifter head L of the die, the wrapper W being transferred from the latter to the former in a manner known in the art by a shift of the suction at the moment of contact. I

The carrier head 22 is divided by a partition 30 into a forward and a rear chamber which communicate through anopening in the partition 30 hav awei edtrap d or 3| n n on a shaft 32. Shaft 32 projects externally from the carrier head, and on an arm 33 clamped thereto has a cam follower 34, or other suitable valve operating device. The underside of carrier arm 35, by means of a bracket 36, carries a wedge shaped cam piece 31 projecting into the path of follower 34. The weight of trap door 3| is so chosen that the suction in the carrier is not sufiicient to lift the same from a stop pin 38 but strong enough to hold it against the partition 3|] after being raised into closing position. Thus the trap door 3| in this case is normally open thereby allowing the suction to act over the entire face of the carrier head 22. At a definite point in the path of travel of carrier head 22, when it is desired to shift the suction from the forward holes 39 to the rear holes 40 so as to augment that on the latter, the door 3| is raised by engagement of follower 34 with cam piece 31 and; then is held closed by the suction until. the

same is, cut off from the carrier head 22 upon delivery of the wrapper W,

When all but the flag end of the wrapper W has been taken off the carrier head 22, as it is being, wound around the cigar bunch at the wrapping station (not shown), a cover 4| movably mounted on the head 22 and normally held in closed position by a spring 42, is opened by engagement with a nozzle (not shown) of a suit; able air blast system provided for that purpose.

The invention above described may be varied in construction within the scope of the claims, for the particular device, selected to illustrate the invention, is but one of many possible con crete embodiments of the same. It is not, therefore, to be restricted to the precise details of the structure shown and described.
